Default Scientific proof that digital sound is bad

From the Diamond Center article:

"With the advent of Direct Stream Digital (DSD) recording, it is now possible
to conclude that the negative effects I have stated above are due not to the
digital process per se but to the mode of achieving it, Pulse Code Modulation
(PCM). For DSD recordings do not have these negative effects.

"Although it was suggested, unfortunately the record industry did not make
analog backups of their digital (PCM) sessions. So now there is a (very
expensive) twenty year hiatus. Hence some SACDs (the CD format for DSD) are
being released which have gone through the PCM process and are as negative as
regular CDs."

Two questions:

Is there a way to be sure of getting purely DSD recordings?

Are DSD CDs -- as opposed to CDs -- as free from these negative artifacts as
SACDs?

It comes from Canada, the evil empire of the north. Need I say more?

Canola oil is GRAS (generally recognized as safe), but I have concluded I
have an idiosyncratic reaction to it.

That's likely. Statements like this:

Especially when we recall that the digital process is no longer confined to
recorded music but is now affecting us nearly all day: TV, radio, telephones
etc. It is we who have become digitalized! show a remarkable lack of
understanding about technology deployment.

PCM began in telecom nearly 20 years prior to Diamond's AES talk. The first
time Americans used PCM audio was in 1962 when Western Electric installed
digital carrier systems in Illinois.

If this is the same Dr. Diamond as was badmouthing Digital back in 1980 and
1985, and it appears that it is, we're basically looking at some very old
news.

JAES, Vol 28, p, 546, 1980 July/Aug and JAES,Vol.33, No.12, 1985 December

Dr. Diamond's claims fail the independent duplication test. Other
independent experimenters fail to duplicate his results, even when
instructed in the use of his procedures by Dr. Diamond.

Canola oil is a GMA food. That is the biological equivalent to
digitizing the DNA of the rape seed.

They now have a new *dithered* Canola oil, which tastes very much like
the old analog Canola oil. They are going to run an ABX taste test on
the old and the new, Canola oil to see which one causes the least
stress.

Of course that's another one of your self-righteous crazy lies, Yustabe.

The problem with Dr. Diamond's silly claims and pseudoscience is not the
idea that music soothes stress and makes one feel better, but rather that
good quality digitization somehow reduces the ability of music to soothe
stress and make one feel better.

If anything, removing the rumble, tics, and audible distortion in inherent
in vinyl, and the audible coloration, hiss, distortion and hum that often
accompany the use of vacuum tubes, greatly enhances the ability of music to
soothe stress
and make one feel better.

If one wants to remove audible rumble one can simply start by getting a

want to get rid of tics buy better records and take care of them. Do tell us

I was listening to Kate, Shins, Etc, Gabriel, and a few other albums
I got recently last night. It was interesting to note how quiet the better
pressings
are. No audible rumble in them. I think what most people perceive
as rumble is not due to the turntable but the quality or cleanliness
of the pressing.

I have a Mangione on right now that has great bass, and the cymbals are so
focused it's incredible. Album Title is "Feels So Good." A&M SP 4658
This is not even any kind of 'special' pressing, just a run of the mill
release.
Still sounds good to me, there is no 'rumble' or tics and pops on this
thing.

I think you misunderstand my position.

Here is something that says that digital music digital is helpful.

http://www.yamaha.com/yamahavgn/CDA/...53 DY,00.html


"MEADVILLE, PA (November 14, 2003) — The employee dissatisfaction,
burnout and rampant turnover that threaten one of America's most stress-prone
industries — long-term care — may have a solution in one of man's oldest
activities, according to a new scientific study. Researchers have found
that a specific Recreational Music-making (RMM) program drastically
reduced employee burnout and mood disturbances with huge projected economic
benefits for the long-term care industry."

"A groundbreaking study, funded by Yamaha Corporation of America with
participation by REMO and published in the Fall/Winter 2003 issue of
Advances in Mind-Body Medicine, demonstrates that a six-week program of
Recreational Music-making not only reduced burnout in long-term care workers,
but also reduced Total Mood Disturbance by 46 percent. Using industry-wide
human resources data, researchers projected that this improvement could
result in an 18.3 percent reduction in employee turnover, which would
save the average 100-bed facility more than $89,000 a year-and the entire
long-term care industry as much as $1.46 billion annually. Actual reductions
in turnover at Wesbury United Methodist Retirement Community, the center
where the study took place, exceeded the research projections."

"The study's protocol was based upon Group Empowerment
Drumming, coupled with exercises on a digital piano..."

Depends on its spectral content. However, the best turntable in the world
won't reduce well-known sources of low frequency noise in LPs, such as
"grain noise" and rumble from the cutting lathe.

With indirectly heated tubes, there's no need for using DC on the

The hum of my power amps is -80 dB with AC on the heaters.

DHT amps *must* use DC on all heaters, as is the case for over 40
years now.

Given that I frequently find SS power amps with all forms of noise including
hum 110 dB down, this seems like it could be a problem. Hum and noise in
power amps is more likely to be a problem than with say, a preamp, because
there is no volume control following the noise source in the power amp.
Therefore -80dB hum and noise referred to full output (say 20 dBW) is
effectively only -60 dB down when referred to a lower but common listening
level of 1 watt.

DHT amps *must* use DC on all heaters, as is the case for over 40
years now.


Because SS rectifiers and regulators are so common, so effective and so
cheap, it's hard to explain why a quality tubed amp wouldn't use DC filament
supplies on all tubes that pass audio. DC operation also extends the useful
life of tubes, as does effective voltage regulation.

Default Scientific proof that digital sound is bad

Any time you want to compare hearing acuity Arny say the word. Every
time I make the challenge you make excuses.

Tell me what you can do in terms of resolving small differences in DBTs at
www.pcabx.com . More specifically, http://www.pcabx.com/training/index.htm
.


IOW you are still all talk and you don't want to take a hearing test and let
the results be known on RAO.

"MEADVILLE, PA (November 14, 2003) — The employee dissatisfaction,
burnout and rampant turnover that threaten one of America's most stress-prone
industries — long-term care — may have a solution in one of man's oldest
activities, according to a new scientific study. Researchers have found
that a specific Recreational Music-making (RMM) program drastically
reduced employee burnout and mood disturbances with huge projected economic
benefits for the long-term care industry."

"A groundbreaking study, funded by Yamaha Corporation of America with
participation by REMO and published in the Fall/Winter 2003 issue of
Advances in Mind-Body Medicine, demonstrates that a six-week program of
Recreational Music-making not only reduced burnout in long-term care workers,
but also reduced Total Mood Disturbance by 46 percent. Using industry-wide
human resources data, researchers projected that this improvement could
result in an 18.3 percent reduction in employee turnover, which would
save the average 100-bed facility more than $89,000 a year-and the entire
long-term care industry as much as $1.46 billion annually. Actual reductions
in turnover at Wesbury United Methodist Retirement Community, the center
where the study took place, exceeded the research projections."

"The study's protocol was based upon Group Empowerment
Drumming, coupled with exercises on a digital piano..."


I daresay the results don't depend on "digital music".

If one wants to remove audible rumble one can simply start by
getting a tuntable that doesn't suffer from this problem as does
Arny's table..


There ain't no such thing if you use a turntable instead of the
funny-sounding thing that sockpuppet wheel mentioned.


How many db down does rumble have to be to
be inaudible?


Depends on its spectral content. However, the best turntable in the world
won't reduce well-known sources of low frequency noise in LPs, such as
"grain noise" and rumble from the cutting lathe.


Don't obfuscate. We're talking turntable rumble. Can turntable
induced rumble be below audible levels? We both know the answer is
yes.

The prerequisite Middius dupe smart-ass, confrontory, meaningless posturing.

We're talking turntable rumble.


Which is difficult or impossible to audibly or measurably distinguish from
the other two sources.

Never ever heard such a thing in my life. Or rather, I never heard the
absence of some kind of low-frequency grinding noise while listening to
vinyl at listening levels that I prefer.

We both know the answer is yes.


Yeah, sure. Oh by the way, keep on believing them lies that Marc Phillips
tells you!
